Abstract

Purpose: Large ventral hernias can be associated with significant loss of domain, and preoperative Botulinum Toxin A (BTA) has been suggested as an adjunct therapy to minimize the effects of ventral hernia repair and facilitate fascial closure. However, there is often bias in studies involving BTA and its use is associated with significant cost and its efficacy remains unclear.

Methods: We systematically searched Medline, Embase, Cochrane, and ClinicalTrial.gov for propensity-score matched (PSM) studies comparing preoperative BTA and AWR with standard AWR for complex hernias. We pooled odds ratios (ORs) and mean differences with 95% confidence intervals (CIs) to assess outcomes, applying a random-effects model. We used R studio version 4.3.1 for statistical analyses.

Results: We included six studies with PSM comprising 851 patients undergoing AWR. The mean age was 60.5 years, mean BMI was 31.8 kg/m², and 46.5% of patients were male. There were no significant differences between groups regarding fascial closure rate (OR 1.54; 95% CI 0.78 to 3.05; p = 0.21), hernia recurrence (OR 0.81; 95% CI 0.33 to 2.01; p = 0.65), component separation (OR 1.50; 95% CI 0.54 to 4.14 p = 0.4), surgical site infections and occurrences (OR 1.31; 95% CI 0.34 to 5.00; p = 0.70), length of hospital stay, or operation time. The Trial Sequential Analysis (TSA) indicated that none of the outcomes reached the necessary sample size for a definitive conclusion.

Conclusions: Preoperative BTA did not offer significant benefits in AWR of complex incisional hernia repairs. However, TSA showed that the required sample size was not achieved.

期刊介绍： Hernia was founded in 1997 by Jean P. Chevrel with the purpose of promoting clinical studies and basic research as they apply to groin hernias and the abdominal wall . Since that time, a true revolution in the field of hernia studies has transformed the field from a ”simple” disease to one that is very specialized. While the majority of surgeries for primary inguinal and abdominal wall hernia are performed in hospitals worldwide, complex situations such as multi recurrences, complications, abdominal wall reconstructions and others are being studied and treated in specialist centers. As a result, major institutions and societies are creating specific parameters and criteria to better address the complexities of hernia surgery. Hernia is a journal written by surgeons who have made abdominal wall surgery their specific field of interest, but we will consider publishing content from any surgeon who wishes to improve the science of this field. The Journal aims to ensure that hernia surgery is safer and easier for surgeons as well as patients, and provides a forum to all surgeons in the exchange of new ideas, results, and important research that is the basis of professional activity.
